k@ne end of said crank issecured to the disc 36 as by means of a pin 49 .while the other end of said crank is guided in its movement .by the pin 50, permanently arranged in and operating in the slot 48.-' Y

For actuating the crank 47 to rotatethe disc, I provide key controlled means and manually operable means, said means 'being respectively disposedon opposite sides ofkv the lock.. The key controlled means consist ofa headed shaft 51 pivoted to the cover 44 and maintained inplace by the head 52von one end thereof and operating arms 53 and 54 ontheotherend thereof Vand arranged near the inner face of the cover. The arm 53 is of suiiicient length toenter the upper enlarged portion 55 of the slot. 56. in Ythe crank 47 and thereby, to actuate said .crank on the rotation ofA the sha-ft51. The arm 54 is bent asuflicient distance towards the interior of the casing/to engage theldeprejssed portion 57 of the detent lever 58 which is pivoted tothe casing about the Apin 59.v Since the shaft 51 is designed to rotate through a complete revolution in the locking` operation and also, during the'unlocking operation, it is desi-7rable thatthe .arm 54 also clear the crank 4: l Y A Toward this end, the arm 54 isfbent in wardly as previouslydescribed, so asto pass interiorly `of the crank 47 When the shaft 51 is rotated and the depressed portion 57 of the lever 58 is made slightly ynarrower lthan the remainder of .said lever 4on the edge Ynearest the cover 44 whereby the armv 53, does not engage said lever on the rotation of the shaft51. n y. K The end 60 of saidglever 58 is urged by the spring 61 into the notches 37 and-38 respectively in the locked and unlocked positions of the bolt'35. Said springis mounted upon a suitable post 64, one end 62 thereof abutting against the upper wall 2O of vthek casinggand the other end 63 engaging the upper surface of the lever 58. j A

Itwill be seen that as the shaft 51 is `rotated by means of a suitable key, the arm 53 engages the leftedge of the enlarged. slot 55 as viewed in Fig. 2 and'carries said crank to theleftthe crank being guided in its movement by the pin 50.1y As said crank moves, the disc 36 and the bolt 35 are rotated and the lock is thereby unlocked, provided that, the end `6O-of thelever 58 is removed from the notch 37. a This is accomplished by the arm 54 which engages the depressed portion57 ofthe leverand raisessaid; lever out of a notch 37 at the same time that movement offthe crank-47 is begun. As the shaft 51 is further rotated back to its initial position, the arm 53 leaves the notch 55 and the arm 54 passes to the right of the depressed portion 57. Further rotation of the shaft 51 brings the arm 54 to its lowermost position to the interior of the rcrank 47 while the arm 5,3 passes the cut out portion at the edge of the lever 58 vvherebythe parts may be returned to their initial positions wherein the armV 53 enters the slot 55 and the arm 54 is arranged, to the left of the depressed portion 57, ready to raise said portion when the rotation of the shaft 51 is reversed to bring the bolt into locking position.

AThe manually operated means for actuatingfthebolt 35 consist of the knob 65 pivotal 'ly mounted in the outer wall42 of the casing l1() and carrying at lthe interior end thereof,

a'bellcrank lever 66'having an arm 67 ad aptedr toengage the depressed portion of the lever 58 and a diametrically opposed arm 68.

. Said arm 68 terminates in a bent portion 69 permanently arranged in the reduced portion of. the slot 56 and spaced from the center of rotation thereof asuiiicient distance so that the arm 54 does not-interfere with said bent portion when the shaft 51 is rotated.

' Itwill beseen that when it is desired to op* erate the bolt 35, the knob 65 is turned 'whereupon the* armi.; 67 of the bell crank Ilever 66 raises the lever 58 out of the notch in the disc 36, *freeing` said disc for rotationfby the crank 47 whenthe bent end 69 operates said crank. Itwill alsobe noted that the boltA 35 is made of sufcient length to passcompletely through the" casingextensions 13, 14 and 15 and through the keeper lugs 31 and 32, the end 7 0 of said .-boltpassing into the casing at the point of connection between said casing and the extension 13 whereby the end ofy theV bolt is nowhere `exposed but a continuous solid bar of metal extends across the juncture of the door and the door frame.

Itvvill further be seen that I have provided an. `extremely simple lock, ycapableof being economically manufactured `in large quantities'and adapted -to be easily assembled and disassembled forreplacement and repair,

While I have shown and described an illustrative embodiment of my invention, I' do not wish to beunderstood as limiting myself to thezparticular structure shown and described since I intend to claim my invention as broadlyas may bepermitted by the state kof the prior art 'andA the .scope of the appended claims.
